SPECIFICATION forming part 0f Letters Patent No. 622,726, dated April 11 1899.

Application iiled December 9,1898. Serial N0. 698,708. (No model.)

To all whom it may concern.-

Be it known that I, HENRY C. STEINHOFF, a citizen ofthe United States, and a resident of lVest Hoboken, Hudson county, New Jersey, have invented new and useful Improvements in Gas or Oil Heaters, of which the following is a specification;

This invention relates to a gas or oil heater or stove which supplies the burner with heated air and causes the hot air while rising in the combustion-chamber to become thoroughly impregnated with moisture.

The invention consists in the various features of construction fully pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation, partly broken away, of a gasheater embodying my invention; Fig. 2, a vertical section on line 2 2, Fig. l, with top h removed; Fig. 3, a horizontalV section on line 3 3, Eig. l; and Eig. 4, a plan of the base with plate g removed.

The body of the stove is composed of two concentric shells a and b, both open at the bottom and between which an annular airspace c is formed, which extends entirely around the combustion-chamber d, inclosed by the inner shell Z7. Oold airis admitted to this air-space or downtake-llue o by upper openings o. in the outer shell a, the air being drawn down the flue and around the lower free e'dge of the inner shell ZJ into the combustion-chamber d, so as to thus become heated and tosupply the burner e, located in chamber d, with warm air.

j' is the annular base of the stove, supported upon legs f and having a top plate g, upon which the outer shell d is set. The top plate g is provided with a diametrically-extending bridge-piece g', spanning its central opening and constituting a support for the lower notched edge of the inner shell b, so as not to impede the flow of hot air around such edge. An upper flanged ring h2, supported on the shells a b, is provided with a dividingflange h between such shells andfis by bolts fzl and nuts t" connected to the bridge g', so that in this way all the parts of the stove are properly assembled. Upon the inner flange of the ring h2 the removable open-work top 7i of the stove is seated.

The bridge g' is centrally perforated to admit the elbow of the gas-pipe j, which pipe may be provided outside of the stove with an auxiliary or pilot burner j', which when ignited ignites the main burner e through perforations a2 b2 in shells d Z2.

Below the burner e there is hung within the base f and below the open top plate g a water-pan k, from which the vapors may freely rise into the combustion-chamber d through the central opening of the plate g. A filling# opening g2 in this plate permits the water in pan k to be replenished.

As the burner e is ignited,'it will heat the air in chamber d, and thus induce a flow of air through openings d', down flue c, around the lower edge of shell l), through opentop plate g, over the water in pan it', and into the lower end of chamber CZ, thus effecting a preliminary heating of the air and supplying the burner with such heated air. The heated air rising in chamber d will be impregnated With vapors from the pan 7c, the water in which is rapidly evaporated by the current of air pass ing Vover it, and the air thus moistened will be discharged into the room through the open top t.

It will be seen that in my improved stove a thorough double-heating effect is obtained and that the hot air while rising throughthe combustion-chamber is thoroughly saturated with moisture, so that a desirable moist heat is given off.

That I claim is-a l. A heater composed of two shells which are open at the bottom and form an inner combustion-chamber and a surrounding downtake-flue communicating with the combustion-chamber at its lower end, combined with a burner within the combustion-chamber, and a water-pian beneath the burner and in oommunication at the lower open end of the shells with the downtake-ilue and also with the combastion-chamber, substantially as specified.

2. A heater composed of a base having an open top plate, a water-pan contained within the base beneath the top plate, two shells which are open at the bottom, and of which one another and also jointly through the open the outer shell is supported upon the top top plate with the Water-pan, substantially as plate and has an upperl air-inlet, means for specified.

supporting the inner shell, and an inclosed HENRY C. STEINHOFF. 5 bu rn er, all bein g so constructed that the down- Witnesses:

take-Hue and combustion-chamber formed by WILLIAM MILLER,

the shells, communicate at the bottom with F. V. BRIESEN.
